A library director feels that this is not true, so he randomly selects 98 borrowers and finds that 80 borrowed books. Can he show that the ALA claim is incorrect? Use α = 0.05. Do not round intermediate steps. (a) State the hypotheses and identify the claim. (b) Find the critical value(s). Round the answer to at least two decimal places. (c) Compute the test value. Round the sample proportion to three decimal places and z score value to at least two decimal places. (d) Make the decision. (e) Summarize the results.
